ATOWHZER.

SPZEGIIEJZGATEOEI forming part of Letters Patent No. 675,556, dated June 4, 1901. Application filed August 8, 1900. Serial No. 26,220- (No modeLl To all whom it may concern.-

Be it known that I, ALFRED CLARKSON, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Atomizers, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a perspective of my improved atomizer, the water-receptacle, drip-trough, and ring thereof being broken away more clearly to show the arrangement of parts. Fig. 2 is a vertical section of said atomizer. The shell is broken away to show the screen contained in the watern'eceptacle. Fig. 3 is a perspective view of the shell, its waternozzles, air-chamber, and air-conduit leading thereto. The interior of said chamber is shown through its broken top.

The object of my invention is to produce an improved apparatus for increasing the moisture in the air of rooms.

My invention consists of a cheap and simple atomizer, the whole or one or more predetermined portions of which maybe operated, as desired.

My improved atomizer is especially useful for increasing and maintaining the desired degree of humidity in rooms where spinning, carding, and weaving cotton and other fabrics is conducted; but it may be used. for many other purposes.

In the drawings illustrating the principle of myinvention and the best mode now known to me of applying that principle, a is the water-receptacle, and a a strainer which covers the bottom and sides of the receptacle a, of which a is the water-inlet. Inlet a is adapted in any suitable manner for attachment to a water-conduit, as heretofore, the bottom of the strainer in the present form of my atomizer resting on supports o in the bottom of receptacle c.

Within strainer a I place a shell I), having an outwardly-projecting flanged top Z), the inwardly-bent peripheral margin 12 of which fits tightly on the brim of receptacle a, thus forming atight coverfor the water-receptacle. Shell 1) is preferably made annular and is provided with a series of shells b on its outer side. The inner ends of the shells b are open toward strainer a and their outer ends are provided with water-outlets, described below. Each shell 6 forms with the side wall of shell I), to which it is joined, a water-passage from the receptacle to the outside air. In the outer side of the top I) there is formed a compartmental turret b, which may have as many air-compartments .r a as desired.

In the present form of the apparatus the turret has two air-compartments, the inner one being marked a; and the outer one 00. Each air-compartment is formed with a suitable number of air-exits, in this case through the side wall of the turret, and each air-exit is in such relation to a water-nozzle that when air under proper pressure is forced through an air-exit past the water-nozzle a rarefaotion of air takes place at that point, so that water is sucked up and sprayed into the room. The air-exits from the air compartment or chamber a: are marked b and those for chamber or are marked N. The water nozzles b are mounted on top I) and their upper ends are inwardly notched at b in line with the aircurrents from air-exits. In its present form the turret is provided with its plurality of independent air-compartments by means of a transverse partition 1) which in this case has edge recesses 19 and inwardly-extending side walls Z7 that form a tight joint at their juncture with the flanged top I) of shell 7). Partition 19 forms a tight joint with the side wall of the turret and is part way between the shell-top b and turret-top Z1 thus forming the two independent air-compartments.

Air is supplied to each chamber or a" of the turret by a suitable air-feeder (1, adapted for connection with a conduit that supplies the air-blast and having a many-way valve which controls the inlet of air to the feeder d, which is provided with an independent air-conduit for each air-chamber. As the present form of apparatus has only two air-chambers 0000, the feeder is made with only two air-conduits on the turret side of the valve; but if the turret were made with, say, three or four more independent air-chambers, then the feeder would be provided with three or four more air-conduits on the turret side of its valve, which would be formed with a corresponding number of ways.

In its present form feeder d has an air-inlet IOO d for connection with a source of air-supply, this inlet being controlled by a three-way valve (1 On the turret side of valve d feeder d is provided with two air-conduits d 01:, conduit d communicating with air-chamber and conduit d communicating with chamber in. WVhen valve d is in the position shown in Figs. 1 and 2, its way d communicates with inlet d, its way 61 with conduit C1 and its way (1 with conduit (1, so that air is simultaneously supplied to the air-chambers 0c and a? and all the atomizing-tubes and air exits brought into simultaneous use; but by turning the valve (1 ninety degrees into the position shown by the dotted valve-handle in Fig. 1 the valveway (1 will communicate with inlet d, valveway (Z with conduit (1, and valveway (1 will be closed by its passage against an imperforate part of the valve-seat d Consequently by such an adjustment of the valve the air-chamber a: will cease to supply air to the vaporizing-tubes opposite its air-exits, while chamber .cr will alone supply air to the vaporizing-tubes opposite its air-exits.

Each conduit d and d is preferably provided with a screen cl", so that dust and dirt may not be carried through the chambers to clog the air-exits thereof, and it is convenient to form each conduit of two members, which are united by a movable coupling 01 To catch the drip of water which may collect about the nozzles, I provide a trough at, having holes leading back into the water-receptacle a. Over and above the nozzles is a removable ring 19 resting on lugs 11 It partially protects the nozzles from dust collecting thereon and prevents the possibility of water being thrown out into the room.

By making the various parts detachable one from another, as set forth, the apparatus may be readily cleaned.

Ifind that the most satisfactory results are obtained by having the air-supply at a pressure varying from twenty to twenty five pounds, that a relative humidity, say, of seventy-five, which is the best for weaving, spinning,and cardingofcotton,canbe quickly created and maintained, and that by screening both water and air there is no clogging of the nozzles and air-exits and the moisture and air thrown into the room are freed from impurities deleterious to the health of its occupants.

What I claim is 1. The combination, in an atomizer, of a water-receptacle having a plurality of atomizer-nozzles with a plurality of independent air-chambers secured to a cover tightly covering said receptacle, each air-chamber having an air-exit in atomizing relation to an atomizer-nozzle; a plurality of air-conduits, one for each air-chamber; an air-supply-conduit connection formed with a valve-seat and connecting said air-conduits; and a manyway valve in said conduit connection, all operating so the apparatus, as a Whole, may be wholly or partially operative, as desired.
